CC1021RSS

RF Transceiver ICS Overview

The CC1021RSS is a single-chip low-power RF transceiver designed for narrowband systems. It operates in two ISM frequency bands: 402 MHz to 470 MHz and 804 MHz to 960 MHz. The device supports FSK, GFSK, and OOK modulation schemes with a maximum data rate of 153.6 kb/s. It features high sensitivity of -109 dBm and an output power of 5 dBm. Powered by a 2.3 V to 3.6 V supply, it consumes 19.9 mA during reception and 12.3 mA to 27.1 mA during transmission. Housed in a 32-VQFN package, it functions within a temperature range of -40°C to +85°C.

RF Transceiver ICS Feature Summary

• Dual-band operation covering 402-470 MHz and 804-960 MHz ISM frequencies
• Supports FSK, GFSK, and OOK modulation protocols
• Integrated SPI and UART serial interfaces for control
• Low power consumption suitable for battery-operated applications

RF Transceiver ICS Applications

• General ISM band wireless communication
• Remote keyless entry systems
• Alarm system transmitters and receivers
• Industrial monitoring and control links

RF Transceiver ICS Procurement Notes

Verify the specific suffix 'RSST' or 'RSSR' against the required tape-and-reel packaging quantity of 250 units. Confirm that the 32-VQFN EP package matches the PCB footprint requirements. Ensure the operating voltage range of 2.3V to 3.6V aligns with the system design. Check moisture sensitivity level (MSL 3) handling constraints if storage time has elapsed.

RF Transceiver ICS Selection Notes

Select this component for applications requiring dual-band UHF connectivity without external filters. The integrated synthesizer simplifies design compared to multi-chip solutions. Consider the 153.6 kb/s data rate limit when designing protocol stacks. The VQFN package requires careful thermal management due to the exposed pad. Verify antenna matching networks for both 433 MHz and 868/915 MHz bands.

RF Transceiver ICS Part Context

The CC1021 belongs to Texas Instruments' family of low-power RF transceivers. It serves as a cost-effective alternative to more complex SoCs for simple point-to-point or star network topologies. The device integrates a receiver, transmitter, and frequency synthesizer on a single silicon die. It is part of the broader CC10xx series designed for narrowband ISM applications.

RF Transceiver ICS Replacement Considerations

CC1021RSST and CC1021RSSR are pin-compatible variants differing primarily in packaging format. Cross-reference with CC1021T/R-R for reel specifications. No direct functional equivalents exist in other manufacturers' lines with identical dual-band coverage and interface compatibility.
